The pressure plate solenoid [A] energizes while the duplex entrance sensor
[B] is actuated. The pressure plate [C] is lowered during this period. This
prevents the paper stack from being moved by the paper sheet entering the
duplex tray. The positioning roller solenoid [D] energizes after the jogger
fences reach the appropriate paper position. The positioning roller [E] is
lowered and is rotating as a result of main motor drive. The paper sheet
entering the duplex tray is transported by the positioning roller to the duplex
paper feed position. The positioning roller solenoid turns off and the
positioning roller is lifted up when the paper sheet hits the separation belts [F].
